Growing a licorice plant at home brings a touch of natural sweetness to your garden or indoor space. Not only does it offer edible roots with a familiar flavor, but it’s also a hardy, low-maintenance herb that thrives with minimal care.
If you’ve ever sipped a soothing cup of licorice tea or enjoyed a piece of natural candy, you’ve likely tasted the magic of the licorice plant. But did you know you can grow this sweet, aromatic herb right at home? Whether you’re a seasoned gardener or just starting out, the licorice plant (Glycyrrhiza glabra) is a rewarding addition to your green space. It’s not only beautiful with its feathery foliage and delicate purple flowers, but it also offers a natural source of sweetness that’s free from refined sugars.
Unlike the artificial black licorice candy many of us remember from childhood, real licorice comes from the root of a perennial herb native to Southern Europe and parts of Asia. The compound responsible for its signature flavor—glycyrrhizin—is naturally occurring and much sweeter than sugar. This makes the licorice plant a fantastic option for those looking to reduce processed sugar in their diet while still enjoying rich, sweet flavors in teas, desserts, and even homemade syrups.

Why Grow a Licorice Plant at Home?
Growing your own licorice plant means having a sustainable, organic source of natural sweetness just steps from your kitchen. It’s a multipurpose herb that blends beauty with function. The plant grows up to 3–5 feet tall, with lush green leaves and spiky lavender blooms that attract beneficial pollinators like bees and butterflies. This makes it not only useful for you but also supportive of local ecosystems.
One of the biggest advantages of cultivating licorice at home is control over what goes into your food. Store-bought licorice products often contain artificial flavors, high-fructose corn syrup, or other additives. By growing your own, you ensure purity and freshness. Plus, harvesting your own roots gives you a deeper connection to your food—something that’s increasingly rare in today’s fast-paced world.
Another benefit? Licorice has been used in traditional medicine for centuries. It’s known for its soothing effects on the throat and digestive system. While we’re not suggesting it as a medical treatment, many people enjoy licorice root tea for its calming properties. Growing it yourself means you can enjoy these benefits naturally and sustainably.
Choosing the Right Licorice Plant Variety
While Glycyrrhiza glabra is the most common species grown for culinary and medicinal use, there are a few related varieties worth noting. True licorice (G. glabra) is the one you’ll want for harvesting roots. It’s a hardy perennial that returns year after year in the right conditions.
There’s also a plant commonly called “licorice plant” that’s actually unrelated—Helichrysum petiolare, also known as the trailing licorice plant or Italian everlasting. This one is grown more for its silvery foliage and ground-covering habit than for edible roots. It’s often used in hanging baskets and doesn’t produce the sweet root you’re looking for. So be sure to check the scientific name when purchasing to avoid confusion.
For home growers, stick with Glycyrrhiza glabra. It’s available from reputable herb nurseries and online seed suppliers. You can start it from seeds, but many gardeners prefer buying young plants for a faster start. Seeds can take several weeks to germinate and require scarification (lightly scratching the seed coat) to improve sprouting rates.
How to Plant and Care for Your Licorice Plant
Licorice plants love warmth and sunlight. They thrive in USDA hardiness zones 7–10, but can be grown in containers and brought indoors in colder climates. If you live in a cooler region, consider growing it as a potted plant that you can move inside during winter.
Sunlight and Location
Choose a spot that gets at least 6–8 hours of direct sunlight daily. A south-facing window works well for indoor growing, or a sunny corner of your garden or patio. Licorice doesn’t do well in shade—its growth slows, and the roots won’t develop properly.
Soil and Planting
Well-drained soil is essential. Licorice dislikes “wet feet,” so avoid heavy clay or waterlogged areas. A mix of garden soil, compost, and sand or perlite works great. If planting in a container, use a high-quality potting mix with good drainage holes.
Plant seeds or seedlings about 1/4 inch deep and space them 18–24 inches apart. If starting from seed, soak them overnight and gently nick the seed coat with sandpaper to help water penetrate. Germination can take 2–6 weeks, so be patient.
Watering and Feeding
Water regularly during the growing season, keeping the soil moist but not soggy. Once established, licorice is fairly drought-tolerant, but consistent moisture helps root development. Reduce watering in winter when the plant is dormant.
Feed your licorice plant once a month during spring and summer with a balanced organic fertilizer. Compost or worm castings also work well. Avoid high-nitrogen fertilizers, which promote leafy growth at the expense of root development.
Pruning and Maintenance
Prune back the plant in late winter or early spring to encourage bushier growth and prevent it from becoming leggy. Remove any dead or damaged stems. Licorice can spread through underground runners, so consider using a root barrier if planting in the ground to keep it contained.
Harvesting and Using Licorice Roots
Patience is key when growing licorice. The roots take 2–3 years to reach full potency and sweetness. Harvest in the fall after the plant has gone dormant. Use a garden fork to gently loosen the soil around the base and carefully lift the roots.
Wash the roots thoroughly and cut them into small pieces. You can dry them in a dehydrator or air-dry them in a warm, dark place. Once dry, store in an airtight container away from light and moisture.
Ways to Use Your Homegrown Licorice
- Tea: Steep 1–2 teaspoons of dried root in hot water for 10 minutes. Sweeten naturally with honey if desired.
- Tinctures and Extracts: Soak chopped roots in alcohol (like vodka) for several weeks to make a homemade licorice extract.
- Baking: Grind dried root into a powder and use as a natural sweetener in cookies, cakes, or energy bars.
- Syrups: Simmer roots in water, strain, and reduce to make a thick, sweet syrup for drizzling on pancakes or desserts.
Always use licorice in moderation. Excessive consumption can lead to side effects like high blood pressure or low potassium levels, especially in sensitive individuals. Pregnant women and people with certain health conditions should consult a healthcare provider before regular use.
Growing Licorice in Containers
Don’t have a garden? No problem. Licorice grows beautifully in containers, making it perfect for balconies, patios, or sunny indoor spaces. Choose a pot at least 12–14 inches deep and wide, with excellent drainage.
Use a light, well-draining potting mix and place the container in a spot that gets plenty of sunlight. Water when the top inch of soil feels dry. Since container plants dry out faster, check moisture levels regularly, especially in summer.
Container-grown licorice may not produce as large a root system as those in the ground, but you’ll still get usable roots after a couple of years. Plus, it’s easier to control spread and move the plant as needed.
Pair your licorice plant with other herbs like rosemary or sage in a mixed herb garden. These Mediterranean herbs share similar sun and soil needs, creating a harmonious and aromatic container garden.
Common Problems and Solutions
Licorice is generally pest-resistant, but it can face a few challenges:
- Aphids: These tiny insects may appear on new growth. Rinse them off with water or use insecticidal soap.
- Powdery Mildew: In humid conditions, white fungal patches may form on leaves. Improve air circulation and avoid overhead watering.
- Root Rot: Caused by overwatering or poor drainage. Ensure your soil or potting mix drains well and let the top layer dry between waterings.
- Slow Growth: Often due to insufficient light or nutrients. Move to a sunnier spot and feed monthly during the growing season.
With proper care, your licorice plant can live and produce for many years. It’s a long-term investment in flavor and wellness.
